Highlights

❖ ATP 2043 in the overlapping Surat and Bowen Basins officially granted to Galilee Energy Limited

(100%), effective 1st August 2019 for a total term of 6 years.

❖ 504 petajoules (“PJ”) of coal seam gas 2C Contingent Gas Resource independently certified in

ATP 2043 in the Walloon Subgroup of the Surat Basin.

❖ Boosts total company 2C Contingent Gas Resource booking to 3,012 PJ.

❖ ATP 2043 is strategically located less than 10km from existing production and facilities enabling

accelerated access to market.

❖ Additional resource potential identified through conventional gas and oil traps.

❖ Initial work program has commenced with planning underway for the reprocessing of existing 2D

seismic.

Galilee Energy Limited (ASX:GLL) (“Galilee”) has been officially granted operatorship and 100% working

interest in the Authority to Prospect - ATP 2043 in the overlapping Surat and Bowen Basins, effective 1st

August 2019 for a term of 6 years. The acreage was made available for tender as part of the Queensland

Government’s recent release of new petroleum resource areas, designed to stimulate oil and gas

exploration in Queensland and provide sustainable benefits to local communities and the broader

Queensland economy.

ATP 2043 is a 384km2, high quality exploration tenure with dual prospectivity within both the world-class

Walloon Subgroup coal seam gas (“CSG”) fairway and the oil and gas prone eastern flank of the Taroom

Trough in the Bowen Basin. A total of 504 PJ of CSG 2C Contingent Gas Resources has been

independently certified in the Walloon Subgroup as at 1st August 2019 by MHA Petroleum Consultants

(“MHA”), validating the material prospectivity and value of this acreage.

ASX/MEDIA ANNOUNCEMENT

MHA conducted an independent evaluation and estimation of the Walloon Subgroup CSG Contingent

Gas Resources in ATP 2043 using a probabilistic method, whereby individual property ranges and

distributions were determined for the key coal parameters with calculations then run through a Monte

Carlo simulation. Additional conventional oil and gas prospectivity has been identified within the permit

area, however this Contingent Resource estimate is limited to the Walloons CSG only.

This independent evaluation generated values for the 1C (low estimate), 2C (best estimate) and 3C (high

estimate) Contingent Gas Resources as per industry standard guidelines (Table 1).

Table 1. Galilee Energy Contingent Gas Resource+ estimates.

The addition of ATP 2043 to Galilee’s portfolio increases the company’s 2C Contingent Gas Resource to

a material 3,012 PJ. This further elevates Galilee’s position as one of the leading, uncontracted Resource

holders on the Australian east coast with clear channels to market as evidenced by the strong progress

Jemena have made with the proposed Galilee Gas Pipeline, in addition to the access Galilee will have to

existing infrastructure in the Surat Basin.

Galilee Managing Director Peter Lansom stated, “The independently evaluated 2C Contingent Gas

Resource estimate for ATP 2043 confirms the very high quality and strategic value of this permit, which

is close to existing infrastructure and provides the capability to deliver material CSG and conventional oil

and gas reserves to a structurally short east coast gas market. This latest tender release and award to

Galilee is also further testament to the Queensland Government’s commitment to stimulating oil and gas

investment in the state and providing financial benefits to both local communities and the broader state.”

Galilee was successful with its targeted approach for this high-graded block and was awarded the

acreage following a non-cash consideration, competitive tender process. The acreage is less than 10

km from established CSG production facilities and directly adjacent to the south of the Ironbark CSG

asset which was recently acquired by APLNG for $231 million. In addition, the regionally significant

Moonie oil field is located only 25km to the southwest on the Moonie-Goondiwindi Fault System, which

directly links the Moonie Field into the central reaches of ATP 2043. It is this same fault system that is

expected to provide considerable permeability enhancement to the Walloon Subgroup coals.

ASX/MEDIA ANNOUNCEMENT

The initial work program for ATP 2043 has commenced with planning underway for the reprocessing of

existing 2D seismic and planned exploration core-hole drilling. ATP 2043 is significantly under-explored

and will benefit greatly from Galilee applying contemporary exploration technology to advance the

understanding of this highly prospective area.

Galilee will leverage the experience of its senior management team who have extensive Surat Basin

CSG exploration and development experience to mature the Resources as efficiently as possible.

Galilee’s capability in this regard is well proven in the Company’s ATP 2019 permit in the Galilee Basin

as evidenced by the Glenaras Gas Project with the Glenaras multi-lateral pilot having recently been

commissioned and which is now progressing towards its goal of achieving commercial gas rates and a

maiden Reserves booking for both the company and the Galilee Basin.

Importantly Galilee has sufficient resources in place to drive both ATP 2019 and this Surat Basin acreage

forward in parallel.

Disclosure under ASX Listing 5.33 Requirements

LR 5.33.1:

The type of permit in which the contingent resources the subject of this announcement is located in, is an Authority to

Prospect issued under the Petroleum and Gas (Safety and Production) Act 2004.

LR 5.33.2:

The Walloon Subgroup is the primary coal seam gas play in ATP 2043 and is present across the entire block. The potential

existence of a significant quantity of recoverable CSG is supported by the location of the ATP within the Walloon Subgroup

fairway, and the data collected from coal cores and tests from wells within, and in the vicinity of, the ATP. The Walloon

Subgroup is approximately 300m in gross thickness across the ATP, and dips generally from the northeast to the

southwest. Based on well control, the coal seams are expected to be at depths, which is within the economic range of coal

seam gas production as proven elsewhere in the region.

LR 5.33.3:

MHA conducted an independent evaluation and estimation of the Walloon Subgroup CSG contingent resources in ATP

2043 using a probabilistic method. The contingent resources estimated are within the sub-class of Development

Unclarified. The PRMS defines this sub-class as having potential for eventual commercial development, but further

appraisal and evaluation activities are required to clarify the potential for eventual commercial development. The key

contingency preventing these contingent resources from being classified as reserves at this time is the permeability and

productivity of the coals. Due to lack of reliable well test data and results, permeability is essentially an unqualified

property. As such, further appraisal and well/production testing is required to quantify this critical parameter.

LR 5.33.4:

The estimates of contingent resources are not contingent on any technology that is currently under development.

LR 5.33.5:

The area of the permit which the continent resources booking relates is the whole of the permit and at this point no

estimate of the number of wells has been determined.

announcement of 1 September 2015, and were estimated using the Deterministic Method with the estimate of contingent

resources for ATP2019 not having been adjusted for commercial risk.

Galilee Energy confirms that it is not aware of any new information or data that materially affects the information included

in the announcement of the 1st of September 2015 and that all of the material assumptions and technical parameters

underpinning the estimates in that announcement continue to apply and have not materially changed.

Contingent Gas Resources detailed in this announcement are (100%) Unrisked Gross

For the purposes of Listing Rule 5.25.3 the Table records the total estimate of contingent resources attributable to Galilee

Energy. No petroleum reserves in any of its permits have been attributed to Galilee Energy.

In accordance with Listing Rule 5.25.2 the contingent resource estimates having been recorded in respect to ATP 2043

and ATP 2019 and as otherwise appearing in Table 1 have been prepared in accordance with the Society of Petroleum

Engineers (“SPE”) 2007 Petroleum Resource Management System (“PRMS”) Guidelines as well as the 2011 Guidelines

for Application of the PRMS approved by the SPE.
